U.S. ethanol stocks are at an all-time high because of high production rates and slow demand.

For the week ending February 12th, the U.S. Energy Information Administration reports U.S. supplies topped 23 million barrels for the first time ever, at 23.218 million, climbing more than 260,000 from the previous week’s all-time high.

The EIA’s next ethanol production and stocks update is out February 24th.
